First T-Storm and Spring Snow

Good morning all,
The weather in Denver had been boring up until a week ago, when we transitioned into an active spring weather pattern. Last Friday we picked up 7" of snow at our house in Thornton, although only 1.7" fell out at Denver International Airport. By Sunday and Monday, temperatures warmed back into the 60s and the snow quickly disappeared. Tuesday afternoon brought some excitement as we had surprisingly strong thunderstorms develop over the Denver area. There was quite a bit of lightning and heavy rain accompanied by graupel as temperatures dropped from the low 50s to the mid 30s. By 5 PM Tuesday, heavy snow kicked in at the rate of 2" per hour in Thornton. By late evening, we had 8" on the ground and ended up with a storm total of 10" by yesterday morning. DIA shared in this storm, with 10.8" of snow "officially". Adding up the moisture from the rain and snow, we picked up 1.40" of precip here in Thornton.

It was a very heavy, wet snow with about 10-12" across most of the Denver metro area, and up to 2 feet in the foothills. Unfortunately, we had significant tree damage in the parks where I work, as well as a broken branch on a tree in our back yard.

Another storm is forecast to move through Colorado tomorrow night. At first, it didn't look too impressive, but now we could have another significant snowfall. Welcome to Denver's "wintry spring"!!



Denver International Airport 58.8"
At our house in Thornton 71.8"

Note: DIA is 20 miles northeast of downtown Denver. Official snow measurements at the airport are usually less, and sometimes much less, than amounts received in the city. The long-term normal at the old Stapleton site near I-70 and Havana St is 61" per season, but DIA probably averages more like 45-50" per season. It will be interesting to compare once a number of years of snow data are collected at the airport.

Good morning OGal and Shoreacres!
Yes, it is good for our water supply. We'll hope to avoid any more tree damage.

Hope you are able to keep up with all that needs to be done in your parks. Stay warm and welcome to "almost Spring". Just remember good for your water system.

Ah - that's the system that was "supposed" to bring us some lightning and thunder, too. It all passed north of me. I did get wakened by the gust front last night, but it's long gone now and sunshine's in the cards for a few days.

Send the next one a little more south! :-)
